Comparison views (2, 3, & 4 images) were rated as more useful than the baseline by 91-100% of participants for DR and 64-82% for wet AMD. There was no significant difference in ratings among the three comparison views. User-adjustable encoding was rated as more useful than static depth-encoded images by 75% of participants (CI: 35%-97%, p<0.05) for DR and 73% of participants (CI: 39%-93%, p<0.05) for wet AMD.

Conclusions :
For both clinical scenarios, comparison and user-adjusted depth encoding views of OCT angiography images were rated as providing additional clinical utility over single views and static depth-encoded slabs. Posterior and Outer depth-encoded images were rated among the most clinically useful images for wet AMD. Data suggest that display interface can contribute meaningfully to the clinical utility of OCT angiography data.
